no upper beak--help

I am a newbie with chickens--this hen I am taking care of has very little if any upper beak--see photo--she is doing ok with a deep bowl for her chicken scratch and water and this seems to enable her to eat. However I worry she might not be getting everything she needs.

Does anyone have any other suggestions? please do not suggest culling as she is a pet--I was thinking maybe there was something nutritious I could syringe into her everyday. As well--they (she lives with one other hen) keep tipping over the deep bowl and wasting feed. I have the bucket tied up but there are still problems looking for alternate solutions...thanks for any help

In her past life (prior to you) she may have been a production bird and had her beak grievously over trimmed. You can carefully trim back her lower beak just to the quick. This will help somewhat. Also providing soaked layer pellets in a deep bowl a couple of times a day will also help.

thanks very much for the info and the great links--very helpful--I just made her porridge with an egg (including shell) crushed strawberries and a little cat food mixed in...they both love it! i will make sure she gets this regularly along with a vitamin. thanks again
